Claim of property

Hi, I am a married woman. I have been married for 3 years and since then staying in my newly constructed 3 floored house of my in laws. Ever since I came into this house my mother in law started abusing me mentally and my father in law is in full support of her .Every time both my father in law and mother in law tell us(me and my husband) to leave the house despite of contributing a lump sum amount for the loan of the house and fooding and other cost. The house loan amount had been issued in the name of my father in law but he and my husband both contributes in that amount(EMI for house loan). Few days back they have mistreated me and for the same they again told to leave the house. My husband when told them that we are contributing towards house loan and fooding and other costs and we are not staying here for free of cost. He also told that we have already made a contribution of 8 to 9 lacs for the above expenditures starting from end of 2014. After hearing this suddenly my father in law told that " No till now you are giving me the rent for which you both are staying in this house and fooding costs separately" And he denied completely the house loan contribution part. Also to let you know that all the members of our house stay together in a single floor where me and my husband stay in one bedroom and rest(father in law, mother in law and brother in law) stay in another bedroom and we share a common hall, kitchen and bathroom. We do have separate balconies for each bedroom. As of now due to all these we've planned to move to a flat after taking all our contributed amounts. Please suggest in this situation what should we do? If we move out of this house shall we get the property share of my father in law. He has only two sons - my husband and my brother in law. Please please hep me out. I am very much in mental trouble due to the harrassments and mental torture I have been going through since after my marriage.
